On one of the sessions each time I were to rebuild or reconfigure the build I would get an "Couldn't find header" error until I've restarted VSCode.
I've meson clean'd my build dir, but that didn't help at a time.
I've renamed the folder and it suddenly began happening.
I then have tried removing the build dir and recreating it in both the terminal and VSCode.
I don't have a minimum reproducible sadly.
